摘要： A Cu-based wear-resistant alloy of a sliding material consists essentially of, by weight, 10-35% Zn, 2-20% Pb, 1-10% Ni, 0.1-1% B and, as required, 0.5-10% of Sn. The alloy can be used under severe conditions of use at elevated speed and temperature with reduced risk of seizure and corrosion. The alloy can be produced by mixing Pb powder and Ni--B alloy powder with Cu--Zn powder or Cu--Zn--Sn alloy powder, or mixing Ni--B alloy powder with Cu--Zn--Pb alloy powder or Cu--Zn--Sn--Pb alloy powder. The alloy can be compacted and sintered to form a sliding member or a composite sliding member is obtained by sintering and integrating the alloy on a steel backing plate optionally having a surface plated with copper.

摘要： A Cu-Pb system composite bearing has three layers including a backing metal, a bearing alloy layer formed on the backing metal, and an overlay formed on the bearing alloy layer. The Cu-Pb bearing alloy contains 2 to 10% Ni and 0.05 to 1.0% B. An example of the composition of the Cu-Pb system bearing alloy consists of 0.5 to 8% Sn, 15 to 30% Pb, 0.2% or less P, 2 to 10% Ni, 0.05 to 1.0% B and the balance of Cu and unavoidable impurities. The Cu-Pb bearing alloy must have a hardness over HV80. Ni and B contained in the bearing alloy decrease the affinity of the Cu-Pb bearing alloy for tin in the overlay of a tin-containing lead alloy. The corrosion resistance of the bearing is improved by plating the both surfaces of the composite bearing with Sn, Pb or an alloy thereof.

摘要： An Ni-based bearing alloy consisting, by weight, of 9-30% Cr, 5-19% Fe, 0.1-1.5% Si, 2-22% Co, 1.4-11.0% Mo, and the balance Ni and incidental impurities, said alloy having a matrix in which hard particles of a Co-Mo-Cr-Si alloy and/or BN are uniformly dispersed in weight ratios of 5 to 35% and not more than 5.0, respectively. The Ni-based alloy matrix provides superior heat resistance. Hard particles of Co-Mo-Cr-Si alloy uniformly dispersed in the matrix improve sliding characteristic with or without uniform dispersion of Bn as a solid lubricant, whereby the bearing alloy exhibits superior heat resistance and sliding characteristic when used in high temperature oxidizing atmosphere.

摘要： A sliding bearing such as a half sliding bearing, a cylindrical bushing and etc. includes a back metal of a three-layer construction composed of a back metal portion of austenitic stainless steel having a thermal expansion coefficient of not less than 15.times.10.sup.-6 /.degree.C., a plated bonding layer formed on the back metal portion, and a plating layer of Cu or a Cu alloy formed on the bonding layer. An alloy layer made of a copper-lead alloy or a lead-bronze alloy is formed on the back metal. With this construction, the alloy layer is positively bonded to the back metal. The austenitic stainless steel is of such a type that the back metal is less subjected to work hardening, and the austenitic stainless steel contains those components which prevent work-inducing martensite transformation.
